To all whom it may concern:

Be: itknown that we, JAMns C. MILLER and ANDREW Isnns, citizens of the United States, and residents of Pittsburgh and Swissvale, respectively, in thecounty' of Allegheny and State of Pennsylvania, have madea new and useful Invention'in Gas Producers, of which'the following is a specification. g i

This invention relates to gas producers and more particularly to that type of pro (lucer having a revolving'body portion.

This application is a division of our application filed June '14, 1919, Serial No. 301,323, which matured into Patent No. 1,373,443 on April 5, 1921. I a

An object of this invention is to-provide continuously operating means for automatically removingthe clinker which forms along the inner surfaceof the revolving body portion of the producer.

This, as well as other objects which will readily appear to those skilled in the producer art, we attain by means of the device described in thespeciflcation and illustrated in the drawings accompanying the same'and forming a part of this application and throughout which similar elements are denoted by like characters.

In the drawings, Figure 1 is a sectional elevation of a portion of a gas producer embodying this invention, Fig. 2 is a top plan view on a reduced scale of the portion shown in Fig. 1 and Fig. 3 is a cross sectional view of the clinker grinder.

The producer proper consists of a cylindrical shell or body portion built up in any suitable manner and as shown in the drawings consists 'of an outer steel shell 6' and "a brick lining 7 supported on an angle 8. The body portion is provided with a Q water-seal trough 9 at its top into which a depending annular flange 10 formed on top plate '11 projects. The top plate or cap 11,

which is stationary, is supported from the operating floor 12 of the producer house by means of suitable supporting feet 13 formed in any suitable manner.

Body 6 is providedwith a support ring 14 adjacent its center and this ring 1S adapted .to rest on suitable support rollers (not shown) carried in suitable standards (not shown) arranged around the producer. Ring 14 is provided with gear teeth 15 111 .preferablytapered as" shown in Fig. 1.

Through this tapered bore a clinker grinder 19 extends. Theclinker grinderconsists of a lowergrinding portion 20 which lies in close proximity to the inner surface of the revolving body of the producer and is preferably fluted on its outer surface as shown in F ig. 8 and'hexa'gonal internally. The

upper extremity of the lower portion'at'21 is preferably cylindrical and fits *with a drive or shrink fit into the lower portionrof the-u-pperypart of. the clinker grinder, which upperpart is preferably externally tapered i as shown in" Fig. 1 -t0 correspond'tov the inner taper of the-flanges 17 and18=.

A flange 22 extends around top plate 11, forming therewith a waterpan. Near opening 16, the flange is continued around the opening in a. small circle" concentric there 'with andthe top-of the flange is machined to form a racefor ballsfl. :Bolted or a otherwise secured to the upper part of the clinker grinderis a plate 23 from which an annular flangefit depends, and, extending into the water pan formed by flange 22 and top plate 11, cooperates therewith to form a seal for the clinker grinder. Plate 23 on its under side is provided with arace for balls 24. Plate 23 also carries a gear 25 which meshes with a gear 15 carried on a hori- Zontal shaft 26 and which, by means of gears 27 28, and 30 is driven from a suitable operating motor. described are so proportioned and arranged as to rotate the. clinker grinder in the same direction as the direction of rotation of the body-of the producer but at a greater peripheral speed so as to tear, fracture, grind or crush and remove clinkers from the viscous clinker mass formed on the inner side of the brick lining 7 as the rotating body moves past the, clinker grinder. Cooling The gears just water is supplied to the interior of the In the present operation of gas producers, it is necessary to shut down the producer every week or oftener for the purpose of cleaning the walls of clinker accumulations. The periods between cleanings depend upon the quality of coal used. The use of my invention eliminates the delay and other expense due to this shutdown and work.

, In accordance with the provisions of the patent statutes we have described the principle of the operation of our invention, together, with the device which we new consider to represent the best embodiment thereof, but we desire to have it understood that the device shown is only illustrative and that the invention can be carried out in other ways.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is- 1. In a gas producer having a revolving body portion and a stationary top, a hollow clinker grinder extending through said top and into the body portion adjacent its inner surface and provided with a fluted grinding portion, a water seal for said clinker grinder, and means for rotating the grinder in the same direction as the body portion but at a different speed to provide grinding action on matter between said body portion and said grinder.

2. In a gas producer, a rotating, cylindrical body, a rotating member spaced from the inner wall of said body and adapted to co-operate therewith to grind clinkers formed on or adjacent said wall. v

3. In a gas producer, a rotating body, a

corrugated member positioned within said body adjacent the inner wall thereof and means forrotating sald member in the same direction as said body but with greater peripheral speed whereby a portion of any substantial clinker mass, formed on said wall, as it contacts with said member is cut or torn away from the mass and said wall.

4. The method of preventing the accumulation of clinkers 0n the interior wall of a gas producer having a rotating body which consists in rotating aroughened element in close proximity to said wall while the producer is operating so as to grind the clinker mass adhering to the producer wall.-

The method of preventing the accumulation of. clinkers on the interior wall of a gas producer which consists in providing roughened element in closeproximity to the wall and providing relative surface movement between said element and the wall without bodily movement of said element from said wall so as to continuously grind the1 clinker mass adhering tovthe producer wa 1.

6.111 a gas producer, a body, a member,

movements of the member relative to the,

body wall. v

In testimony whereof, we have hereunto subscribed our names this 1st day of December, 1919.
